Cast Iron Radiator Fittings: Removal Tips?

Stew_5 Member Posts: 23
I'm installing a used cast iron radiator that has the nut-half of the pipe union still in it. Removed one by heating w/ oxy/acetylene torch but am nervous about pushing my luck ("crack!, #%*¥@!!) removing the other two. What are my chances of finding the other side of the existing unions? Nut is 3/4" pipe thread and I'm tempted to just use a 3/4 cu male adaptor..... Probably not a good idea. ?

If I go back to heating to red hot and removing them, any voices of experience out there? Like how big an area around the fitting should I pre-heat w/ torch to prevent cracking?
